Rel attribute
Extracted from the Wikipedia article Link relation.
In HTML these are designated with the rel attribute on link, a, or area elements. Example uses include the standard way of referencing CSS, <link rel="stylesheet" href="example.css" />, which indicates that the external resource linked to with the href attribute is a stylesheet, so a web browser will generally fetch this file to render the page. Another example is rel="shortcut icon" for the popular favicon icon.
